Genic susceptibility could increase the risk of transient ischemic attack (TIA). The objective of this study is to investigate the relationship between the polymorphism of platelet glycoprotein GPIb α Kozak gene and TIA in Qindao Han population.
The polymorphisms of platelet glycoprotein GPIb α Kozak gene -5T/C in TIA patients and normal control were detected with sequence-specific primers polymerase chain reaction (PCR-SSP).
The prevalence of the CC genotype and C alleles were significantly higher in TIA patients than in the control group (P<0.05). The positive correlation between C allele and TIA was showed by logistic regression analysis (P=0.016).
The -5T/C polymorphism of the platelet glycoprotein GPIb α Kozak gene is implicated in the pathogenesis of TIA. C allele is an independent risk factor for TIA.
基因易感性可能会增加短暂性脑缺血发作（TIA）的风险。本研究的目的是探讨青岛汉族人群中血小板糖蛋白GPIbα Kozak基因多态性与TIA之间的关系。
采用序列特异性引物聚合酶链反应（PCR-SSP）检测TIA患者和正常对照者血小板糖蛋白GPIbα Kozak基因-5T/C的多态性。
TIA患者中CC基因型和C等位基因的发生率显著高于对照组（P<0.05）。Logistic回归分析显示C等位基因与TIA呈正相关（P=0.016）。
血小板糖蛋白GPIbα Kozak基因的-5T/C多态性与TIA的发病机制有关。C等位基因是TIA的独立危险因素。
